Java Programming for Complete Beginners - Java 16 - Step 03 - Java For Loop - Exercise - Sum Upto N Numbers and Sum of D

The video tutorial covers two main exercises: calculating the sum of numbers up to a given number (sum up to north) and calculating the sum of divisors of a number, excluding the number itself and one. The tutorial provides a step-by-step guide on implementing these exercises using loops and conditional statements in Java. It also includes debugging tips to help understand the logic behind the code. The video aims to build foundational skills in programming by introducing basic concepts and gradually moving towards more complex logic.

What is the initial value of the sum variable when calculating the sum of numbers up to a given number?

• 1

• N

• 0

• N/2

Which of the following is a correct condition for the loop to sum numbers up to N?

• i >= N

• i > N

• i <= N

• i < N

What is the purpose of adding a debug point in the code?

• To change the code

• To stop the code execution

• To delete the code

• To understand the code flow

When calculating the sum of divisors, which numbers are excluded?

• The number itself and 1

• All even numbers

• All odd numbers

• Prime numbers

What condition is used to check if a number is a divisor of another number?

• number * i == 0

• number / i == 0

• number % i == 0

• number + i == 0

If the input number is 9, what is the sum of its divisors excluding 1 and 9?

• 9

• 12

• 6

• 3

What is the sum of divisors for the number 6, excluding 1 and 6?

• 9

• 3

• 6

• 5
